DESCRIPTION

63       The  r.region  program  allows  the  user to manage the boundaries of a
64       raster map. These boundaries can be set by the user directly and/or set
65       from  a  region  definition file (stored under the windows directory in
66       the user's current mapset), a raster or vector map, or a 3dview file.
67
68       The align parameter allows to set the current resolution equal to  that
69       of  the  named raster map, and align the boundaries to a row and column
70       edge in the named map.  Alignment only moves  the  existing  boundaries
71       outward  to  the edges of the next nearest cell in the named raster map
72       -- not to the named map's edges.  To perform the latter  function,  use
73       the raster=name option.
74

NOTE

76       After  all  updates have been applied, the raster map's resolution set‐
77       tings are recomputed from the boundaries and the  number  of  rows  and
78       columns in the raster map.
